Thank you! It does appear to be the Denver Art Museum. However, in doing a little research, the Denver Art Museum does not appear to be the work of I.M. Pei. The architect listed for this new addition was architect Daniel Libeskind. Thanks again for naming this building for us. We were going crazy trying to figure it out.

I am going to participate in the world bodypainting championships http://www.bodypainting-festival.com and i am going to dedicate my finalist painting to I.M.Pei because he is my hero.
The theme of the finals is Avant garde, innovation and provocation.
I came up with my painting after seeing a documentary about I. M. Pei and all his great work and his methods of working, about how if he really wants something to be done in a certain way he finds out how to make it work and he encourages his workers to make it happen. This way he does a lot of discoveries for it has never done before.
He even uses NASA technology to build his buildings. And at his age he is still working. That is so awesome.

Yes I was surprised that the ( design, not the building of ) John Hancock tower was attributed to I M Pei rather that SOM but I’ve just been to the Louvre again and have to say well done to his office for a wonderful contribution.
